The DSLR camera users, both amateur and
professional photographers must have been very familiar with Sigma, third-party
lens manufacturers which is very popular among owners of Canon or Nikon DSLR
camera. However, Sigma has also made a good camera compact-system cameras and
DSLR type for example Sigma SD1 and SD15. You can also try the DP3 Merrilla compact digital camera, also made ​​by Sigma. Although the Sigma
camera are not as famous as Sony or Olympus cameras, but you certainly will be
amazed with this new camera, the Sigma
DP2 Quattro and other Quattro series.

By making
the Sigma DP Quattro, perhaps Sigma wants to solidify its image in the world of
photography, then in addition to successfully create various types of lenses,
the Sigma also able to make digital cameras such as Panasonic, Pentax or Samsung.
Sigma DP series is launch 3 series; The DP Quattro series will Consist of three
models: the DP1 with a 28mm fixed focal length, 45mm at DP2 , and DP3 at 75mm (35mm equivalent all ).

All lenses
have an aperture range of f/2.8-16, DP1 and DP2 with the having a nine - blade
diaphragm and a seven - blade diaphragm in the DP3. Lens construction is nine
elements in eight groups (DP1), eight elements in six groups (DP2), and 10
elements in eight groups (DP3).

The lens specifications, in terms of numbers of
groups and elements, and minimum focusing distances, remain unchanged from the
'Merrill' models. All three models will have 920k dot rear LCDs and 9-point
contrast-detection autofocus systems.
You can enjoy improved optics, ISO performance, image
processing and design.

Works of art camera

The Sigma
DP Quattro is redesigned in
every aspect, including the sensor, engine, lens and body, the DP Quattro
Compact Camera series embodies Sigma’s philosophy of creating cameras that
produce works of art. If you look the specification, then the
cameras are similar to the Sigma Merrills, - fixed 19mm, 30mm, and 50mm f/2.8
lenses paired with Sigma’s unique Foveon APS- C sensor - but the industrial
design is a radical departure from anything else on the market. The Sigma DP2
Quattro is the next generation of its DP series of APS-C sensor, fixed focal
length cameras. The latest, 45mm-equivalent, model features dramatic styling
and a fundamental re-think of the company's Foveon multi-layer sensor design.

Sigma has always released
its compacts in trios: same camera, different prime lenses. The 1st of the three new Quattro cameras will
be released with a 20 MP Foveon X3 sensor, the new faster True III processor
and a 30 f/2.8 lens attached. Sigma has also
made a leap to a faster TRUE III image processor. There is another surprise
that you will find, there's also an opticalviewfinder available for purists,
which should work well with the fixed lenses. The DP2 Quattro will come with a
30mm f/2.8 general purpose lens, while the DP3 and DP1 will respectively carry
19mm wide-angle and 50mm telephoto
optics. The image quality that Foveon
chips output is incredibly detailed. The new Foveon X3 Quattro offers an
even higher level of image purity with a 30% increase in resolution to the
previous Foveon sensor, sure to bring about new experiences in your
photography.

If you look at the shape of this camera,
very different from the previous Sigma cameras, even appears in contrast to the
compact-system camera ever you known, with a very unusual shape. You could also
say that this form of the Sigma DP Quattro has almost cinematic body shape is meant
to provide a more balanced feel in the hand than the compact design of its
predecessors. The camera has a wide, relatively thin body with a grip that
bends backwards at about a 45-degree angle.

The camera is made ​​by Sigma is
different from other cameras, Sigma's cameras use a technology called Foveon.
This special sensor has three layers, with each layer sensitive to blue, red or
green. This way the camera has color information from all three channels at
every point in the frame. The result is generally a very sharp, very large
image. Autofocus is greatly improved, continuous shooting times are a little
more usable, and the battery life has more than doubled.The Quattro models will also see vastly
improved battery life when compared to previous DP-series compacts.

If you are interested in the sophistication of the camera
sensor and lens on the Sigma DP Quattro, then what series would you choose out
of the three?
